So, I was bored. I drove 26 to find snow. I got to Buckner Gap 3370 ft and there was a mix. I got to Sam's Gap and there was the beginning of snow with some on the ground in TN. There was more in TN but it diminished quickly.
A few miles outside Erwin, the temp dropped to 30 and it was pouring snow. Snow on the ground and snow on the interstate. A few miles down the road in Erwin was a mix again though there was some on the ground.
I turned around there and got back to Sam's Gap and it was heavy snow on the TN side, but quickly diminished on the NC side.
Bottom line, the cold air in the upper atmosphere is somewhere near Erwin, TN. It was fun to see snow for a little bit.
